Summary
Breast milk promotes beneficial gut bacteria (Bifidobacteria) and reduces harmful bacteria (Enterobacteria) in infants. Formula feeding results in higher levels of Enterobacteria, suggesting breast milk offers protection against infections.
Area of Science:
- Microbiology
- Infant Nutrition
- Gut Microbiome
Context:
- Neonatal gut microbiota development is influenced by feeding type.
- Enterobacteria initially dominate, followed by Bifidobacteria.
Purpose:
- To investigate the impact of breast-feeding versus bottle-feeding on infant fecal bacterial flora.
- To analyze the role of milk physicochemical properties in shaping gut microbiota.
Summary:
- Breast-fed infants showed a decrease in Enterobacteria and a rise in Bifidobacteria. Bottle-fed infants had higher Enterobacteria counts.
- Human milk's low buffering capacity creates an acidic gut environment favoring Bifidobacteria and inhibiting pathogens.
- Formula feeding led to a less acidic gut environment with higher Enterobacteria levels.
Impact:
- Breast feeding promotes a healthier gut microbiome composition in infants.
- This may offer protection against intestinal and systemic infections.
- Findings highlight the importance of breast milk for infant gut health.
